The tight lateral tissues and muscles that have pulled the patella out of place are cut, allowing the patella to resume its normal position.
If the patella has been pulled to one side, the lateral tissue is loosened on one side and tightened on the other.
If your kneecap has been dislocated, there may be a tear in the ligament that attaches the kneecap to the thigh bone.
Surgery involves reconstructing this ligament, normally using donor tissue from another part of your body with anchors into the thigh bone and kneecap.
Tibial tubercle transfer is recommended if there is evidence of existing malalignment of the patella.
Your orthopaedic surgeon cuts a small lump on the shin bone (tibial tuberosity) where the patella tendon connects, and repositions it, so the kneecap is centralised. It’s then held in place using metal screws.
You will usually be able to go home the same day as the operation. Your knee should be kept dry for 48 hours after surgery.
You will need crutches for about four to six weeks. How much weight you can bear and how much movement you’re allowed varies according to the amount of surgery you’ve required.
We will give you physiotherapy exercises and you can take over-the-counter painkillers to help with any pain.
If you have had tibial tubercle transfer (TTT): you won’t be able to put any weight on your leg for four to six weeks. You will need to wear a knee brace for at least four weeks. The cut bone itself takes about three months to heal, and it can be six to twelve months before full strength is restored.
